5-2-1 When Demand Controller Method is used
(1) To use Demand Controller Method, before using the PLC Software for demand input or Electric Amount
Count Software, click on the PLC initialize button once to initialize the internal memory.
Note: Do not initialize the memory after the operation has begun, for it will clear all operation data.
(2) Enter the IP address for the PLC software for demand input.
(3) Enter the IP address of the AG-150A to which the demand levels are reported. A maximum of 10
addresses can be registered.
(4) When the energy-save level is set to 0 (It is always set to level 0 in an energy-save control method),
energy-save control will not be performed for the indoor units that show a greater difference between the
set temperature and indoor temperature than the value set in the window on the right.
Make the setting when some type of energy-saving control is effective at energy-save level 0 and the level
of comfort is high on priority list. (Choose between 3 to 9)
5-2-2 When Electric Amount Count PLC Method (Amount Count Software) is used
(1) To use Electric Amount Count PLC Method, before using the PLC Software for demand input or Electric
Amount Count Software, click on the PLC initialize button once to initialize the internal memory.
Note: Do not initialize the memory after the operation has begun, for it will clear all operation data.
(2) Enter the IP address of the electric amount count software.
(3) Select the terminal number of the DI board to which the watt-hour meter is connected. If it is connected to
terminal 2 on DI board 1, select 1-2.
Note: Select an input board from either 1 or 2, and select an input terminal from 0 to F. Choose the terminal to which the watt-hour
meter is connected that is used for peak cut.
(4) Enter the unit of the pulse that the watt-hour meter outputs.
(5) Determine the range of electricity use for each control level (demand level), taking into consideration such
factors as delayed control of the air conditioner. Enter the value that is 10 to 15% below the maximum
demand value (average electric energy value in 30 minutes) in the blank next to Level 4. Decrease the
value by about 10 % for each level below. (The figure on the right shows the system with the maximum
electric energy at 200 kW.)
Note: The best set point depends on the system configuration of the electric equipment and the indoor environment in each
building. Choose appropriate set points accordingly.
Note: The amount of electricity that is actually used may exceed the demand value due to such unexpected incidents as controller
problems or broken transmission lines. Mitsubishi will not be responsible for such incidents.
(6) When the energy-save level is set to 0 (It is always set to level 0 in an energy-save control method),
energy-save control will not be performed for the indoor units that show a greater difference between the
set temperature and indoor temperature than the value set in the window on the right.
Make the setting when some type of energy-saving control is effective at energy-save level 0 and the level
of comfort is high on priority list. (Choose between 3 to 9)
Note: Set the value per pulse according to the measurement meter to be used. To check that the setting is correctly made, firs
t
check both the values measured by the measurement meter and by the measurement controller, and after a certain time,
check that the both values have increased at equal increments. (The value measured by the measurement controller can be
checked on the browser for the administrator.)
